Integracides, 4,4-dimethylergostane triterpenoids, are inhibitors of HIV-1 integrase, a critical enzyme in replication of HIV-1. The chemistry and structure-activity relationship of integracide B and related natural products are described. A charged group, e.g., a sulfate, carboxyl, or amino, is required for the HIV-1 integrase activity. These compounds showed HIV-1 integrase activity with IC(50) values
4,4-二甲基麦角锡烷三萜类化合物,Integracides是HIV-1整合酶(一种在HIV-1复制中的关键酶)的抑制剂。描述了杀虫剂B和相关天然产物的化学和结构-活性关系。HIV-1整合酶活性需要带电荷的基团,例如硫酸根,羧基或氨基。这些化合物显示出HIV-1整合酶活性,IC(50)值在4.8-15μM之间,并且在病毒扩散试验中显示出抗病毒活性,但是只有很小的治疗窗口或没有治疗窗口。
